1 Claim.

The present invention relates to the art of glass cutters and pertains in particular to a manually usable implement or tool, and the essential object of the invention is to provide a specifically improved and novel device which is advantageously usable in scoring so-called pattern glass.

The ordinary or conventional glass cutter for hand use is characterized by a longitudinally elongated body, one end being fashioned to provide a handle and the other end a scoring head,

this being provided with a scoring element usually in the form of a disk or equivalent means. Where it is necessary for the user to follow or trace a prescribed pattern marked on the glass,

the ordinary cutter hides and obscures the pattern line. In reducing to practice the'device forming the subject matter of this invention, I have therefore, devised an arrangement which embodies, in association with the cutting disk, a

sight opening, this serving to afford the necessary visibility required in following the guide lines with accuracy and precision.

A further feature of the invention pertains to a bifurcated cutter head providing the aforementioned sight opening, there being adjoined thereto a laterally offset handle so that the portion of the structure between the head and handle may be adequately fashioned to facilitate a more dependable finger hold.

Other features and advantages will become more readily apparent from the following description and accompanying illustrative drawing.

In the drawing, wherein like numerals are employed to designate like parts throughout the views:

Figure 1 is what may be called a plan view of a glass cutter with its features constructed precisely in accordance with the principles of the present invention.

Figure 2 is a side or edge elevational view of the same.

Figure 3 is a view partly in section and partly in elevation showing the hand hold and the bifurcated head construction.

Referring now to the drawing by distinguishing reference numerals, it will be observed that the longitudinally elongated body is of one-piece construction, any appropriate metal or material being utilized for the purpose. In plan view the head 4 is substantially semi-ovate in configuration. In side view the head is substantially V- shaped and is perfectly fiat or plane on what may be called the work facing side 5. The head is bifurcated to define a slot 6, this functioning as the aforesaid sight opening. The extremities l of the parallel furcations 8 are in close spaced parallelism to accommodate an axle or pin on which the scoring or cutter disk 9 is mounted. The pins function as journals and are rotatable in suitable bearings in the portions 1. The slot 6 5 is in direct longitudinal alignment with the disk so that the work is at all times visible through the medium of said slot and hence it is possible to accurately follow guide lines defining the pattern being scored for glass cutting purposes. 10

The handle [0 is fashioned so that it may be conveniently grasped. It is to be noted however, that the handle is offset in relation to the cutter head, and that at the juncture of the handle and head there is a convex crown portion I I forming 15 a convenient finger rest and opposite to this there is a shoulder I2 forming an abutment. These features II and I2 provide a convenient and safe finger grip which facilitates manipulating the tool and maintaining it in firm contact with the work.

By way of summary, it is to be observed that one outstanding feature and improvement is the bifurcated head construction wherein the space between the furcations defines a longitudinally 25 elongated centralized sight opening, this being in alignment with the glass scoring disk. Because of this it is possible to use the tool in precision work such as is required in pattern glass cutting. Secondly, the offset handle is presumably an improvement in an implement of this type. Particularly the design and formation of the juncture between the offset handle and head, characterized as features II and I2, is a worthy contribution as a component feature of the tool. Therefore, these parts contribute their proportionate share in what is believed tobe an improved glass cutter.

It is thought that the description taken in connection with the drawing will enable a clear understanding of the invention to be had. There- I 40 fore, a more lengthy description is thought unnecessary.

While the preferred embodiment of the invention has been shown and described, it is to be understood that minor changes coming within the field of invention claimed may be resorted to if desired.

I claim: A glass cutter of the class described comprising 5 a longitudinally elongated bifurcated head, a relatively small cutting disk mounted for rotation between the extreme outer ends of the furcations, the existing space between the inner opposed faces of said furcations being in longi- 55 tudinal alignment with the peripheral edge of the cutting disk and the crotch thereof being relatively remote from the cutting disk and defining a longitudinally elongated sight opening, said sight opening in conjunction with the cutting disk facilitating constant inspection of the work to allow the eye of the user to follow a predetermined line pattern, and an off-set handle connected to the inner end of the head, the juncture between the off-set handle and the head forming finger engaging and tool controlling grips.
